摘要:

使用3-氨丙基三乙氧基硅烷和苯基三甲氧基硅烷对ZSM-5分子筛进行不对称修饰, 制备了外表面亲水、 内表面亲油的双亲型分子筛. 将此分子筛作为前驱体, 经过气溶胶发生器处理得到具有双亲性的类气溶胶分子筛. 通过SEM, XRD, FTIR, N2气吸附-脱附实验等对材料进行了表征, 测试并计算了材料的亲水亲油平衡值. 探究了前驱体浓度和载气流量对类气溶胶双亲分子筛粒径和数量的影响.

关键词: ZSM-5, 双亲性, 类气溶胶分子筛

Abstract:

By asymmetric modification of ZSM-5 zeolite with 3-aminopropyltriethoxysilane and phenyltrimethoxy- silane, amphiphilic ZSM-5 zeolite with hydrophilic outer surface and oil-philic inner surface was prepared. The as-prepared zeolite was used as a precursor and processed by a gas-phase amphiphilic generator to obtain an aerosol-like zeolite with amphiphilic properties. The materials were characterized by means of SEM, XRD, FTIR and N2 adsorption. The hydrophilic-lyophilic balance(HLB) of materials was measured and calculated. The effects of different concentrations of precursor and carrier gas flow on the size and quantity of aerosol-like amphiphilic zeolite were investigated.

Key words: ZSM-5, Amphiphilicity, Aerosol-like zeolite
